Application mea March 1, 1912. serial no. 680,998.

T 0 all whom t may concern Be it known that I, CHARLES R. LAMBERT, a citizen of the United States of America, residing at Detroit, in the county 0f Wayne and State of Michigan, have invented certain new and useful Improvements in Vapor-Burner Furnaces, of which the`following is a specication, reference being had therein to the accompanying drawings.

The invention relates to furnaces more particularlydesigned for use in heating of soldering irons, the melting of soft metal and other similar uses.

It is the object of the invention to simplify and cheapen the construction and to this end the invention. consists in the peculiar construction, arrangement and combination of parts as hereinafter set forth.

In the drawings,-Figure l is a side elevation of the furnace; Fig. 2is a perspective view of the hearth and hood construction; Fig. 3 is a longitudinal section there through; and Fig. 4 is a cross section. Fig. 5 is a perspective view of the hearth-plate with its depending iange.

A is a tank for liquid fuel such as gasolene, upon which is mounted on a standardl B, a frame C for supporting the burner, hearth-plate and hood. As heretofore constructed it is usual to make the hearth and hood, as well as the burner, of cast metal. In the present construction they are formed from sheet metal stampings which is not only a cheaper construction to manufacture but reduces the weight of the structure which is desirable as the device is usually carried by hand. In detail, D is a pan struck up from sheet metal to form a bottom and integral sides with rounded corners. The front side is cut-away at E for the passage of the valve stem therethrough, while the bottom of the pan beneath the burner valve is depressed at F to form a starting cup. V-The upper edge of the sides G of this stiffening iiange H which also. forms a support for the hood section I. rIhe latter is also formed from sheet metal stampings having thehorizontal base iiange J and a down-turned marginal flange K, the `latter embracing the flange I-I of the pan. Above the flange J is a conical portion L which is circular at its upper end and is attached by riveting or otherwise to a cast metal stiftening ring M having lugs N projecting inward pan have the outwardly extending therefrom to support a pot or ladle. The front of the hood L is cut-away at O for the insertion of soldering virons or other tools to be heated. There is also a hearth plate P formed of sheet metal which is interposed between the iiange J of the member I and the pan D. This hearth plate projects outward beyond the hood and at its inner end has a down-turned flange Q which separates the combustion chamber from the portion of the pan in which the valve is located. The burner R is preferably of cast construction, being provided with a central air and vapor mixing tube R and slotted tubes R2 on opposite sides thereof connected to the mixing tube by the end cross tube R3. The vaporizer is formed by a tube S which passes through the hood above'the burner but at one side thereof, and then turns downward in front of the fiange Q and is i connected with the inlet valve T. At its opposite end the tube S passes out from the hood and is. connected with a downwardly extending conduit U leading into the tank.

rllhe construction described being almost completely made of wrought metal is less liable to be broken than cast construction and is also lighter and stronger. A suitable carrying handle or bail V is provided, this being` attached to ears W riveted to the opposite sides of the hood below the ring M and there is also a cover X for closing the opening in the ring M when the pot or ladle is not used. Y

As the opening a in the tubes R2 is located at the sides a deiiecting plate Z is provided which as shown has a segmental portion b engaging the tube R and apertured at c to receive a lug d at the center of the member R. The segmental portion terminates in outwardly extending flanges e which are positioned below the plane of the opening a. Adjacent their outer edges these'flanges are provided with legs /f which rest upon the bottom D. Adjacent the middle of the deiecting plate is arranged a. dividing tion la The' construction just' described forms a very effective means of spreading the flame.

What claim as my invention is:

l. In a furnace, the combination with a tank, a standard rising therefrom, a spider frame supported on said standard, a pan secured to said spider frame, burners and a mixing tube in said pan, and a deflectng partiplate'engaging said tube and. having por- Ations vprojecting into operative relationto the burners for the purpose described.

In4 a furnace, the combination with a tanka'nd a standardmounted thereon, of a sheet Vmetal structure mounted Vvon said' standard comprising a pan having a bottomA and integralsides flangedat their upper edge, a

jheartheplate of sheet'l metalvresting on said flange' 'andhaving a depending'flange exff tending into the pan, a hood formed of Y sheet metalhaving a circular opening at the top-thereof and flanged Yat itslower end to rest upon saidY pan and to embrace the flanged edge thereof, and a reinforcing ring of cast metal securedtopthe upper end of said hood. Y Y Y "3.` In afu`rnace,;the combination with a tankvand a standard rising therefrom, of a sheet fmetal structure supported on said standard comprisinga pan'having upwardly extending integral sides flanged at theirfupper edge, a hearth-plate supported at one Y endlof saidpan havinga downward extending flange, a hood arranged above said pan and flanged to rest thereon and to engage Y' the flanged edges ofthe pan, said hood being cut-away over said hearth-plate, a

burner arranged within said pan, a vaporizer extending through said hood, and a vapor #controlling inlet valve arranged beneath said hearth-plate 'andconnected with said va- 'porizen n y AQA; furnace comprising a tank, a standardjrising therefrom, a vspider frame supported fon rsaid standard, a VVpan formed of sheet metal secured to said spider frame hav? ing integral sides and a flanged upper edge, a burner and mixing tube in said pan, an in let valve in. front of said burner, a hearthplate formed of sheet metal having a-down turned flange dividing the portion of said Vpan containing said burner from that containingrsaid inlet valve, a hoodrformed of sheet metal Vabove said panand hearth-plate and flanged for engagement therewith, a

vaporizing-tube passing through said hood y Copies of this` patent may beV obtained for zontal flange resting on said hearth-plate and pan, a down-turned marginal flange, and a tapering upwardly extending body portion,'said body portion being cut-away above said hearth-plate, the upper edge of said body being of circular form and a cast metal reinforcing ring secured to the upper edge of said hood and having inwardly extending lugs thereon for supporting the pot or ladle.

6. In a furnace, the combination with a tank, a standard rising therefrom, a spider frame supported on said standard, a pan secured to said spider frame, a mixing tube in said pan, burners arranged upon opposite sides of said mixing tube, and a delecting plate engaging said tube and having laterally extending portions projecting into operative relation tothe burners, for the purpose described.

7. In a furnace, the combination with the tank of a standard rising therefrom, a spider frame supported on said standard, a sheet metal pan with vflanged upper edge thereon secured to said spider frame, a hood having a corresponding flange and fitting upon said pan, a vaporizing tube above said pan and within-said hood, a mixing tube connected to the vaporizing tube by means of a valve, an end cross tube connecting the vaporizing tube, slotted tubes arranged upon opposite sides of said mixing tube, said slotted tubes being closed at one end and connected to said end cross tube, a deflecting plate having a segmental portion engaging the mixing tube and terminating in outwardly extending flanges positioned below the plane of the openings in the slotted tubes, a dividing partition arranged adjacent the middle of the deflecting plate, and a hearth plate with avdownward vprojecting flange overlying a Vportion of said pan. Y

8. In a furnace, the combination with a hood and panforming a combustion chamber, of a valve positioned therein, a hearth plate positioned in the plane of the meeting edges of said hood and pan, said hearth plate projecting outward beyond the hood and at its inner end having a downturned flange separating said valve from the combustion chamber.

YIn testimony whereof I alix my signature in presence of two witnesses.
